I went for a demo in Airtel Santhome office. My house is in Mandaveli. The person played a 4K Video and the video played non stop without buffering. What is your people suggestion? Should I go for one? Also one more advantage in 4G is for example you choose the 650 plan and exhaust the quota of 3GB before your billing cycle, you can change your plan to 750 ( which gives 4GB limit) so you will get an additional 1GB and you will not be charged both 650 and 750 but only Rs 750 as rental. I experienced the demo of Wi-Fi hotspot which can be connected with 10 devices.
